Re: 4 Tuba 30 Built

And your computer sound card is capable of reproducing 20Hz. Not all sound cards will. Also make sure the amp does not have a low cut filter by reading the specs. play a 20Hz sine wave at 10 volts for 12-24 hours. Hang the driver with bungee cords in free air for the least amount of "noise&quo...

Re: 4 Tuba 30 Built

Ok thank you Grant, I do have the amp and the multimeter but can I use "online tone generator" like this: http://plasticity.szynalski.com/tone-generator.htm or does it have to be a software? Thanks again Whatever works for you is fine :) If you can guarantee internet access for 12 hours, ...

4 Tuba 30 Built

Hello everyone, I have been in this site for sometime, I have bought a few plans but never got to start making any of them. Now as the holidays are around the corner, I have decided to build 4x Tuba 30 approx. 24" wide. I have read the plans a few time and I am confused or do not know how to br...

Re: AutoTuba Plan Question

... but I am trying to keep it small and portable as it's to be taken along a boom box that I made. My boom box is pretty loud with lots of vocals but no hit, no bass, no thump, is kinda missing at least a little of bass or hit to sync with my boom box. The autotuba is still a heavy box. I have tro...

Re: AutoTuba Plan Question

I do want to use 2 - 8" as I will be using this TAT outdoor around a pool area (open field). Like Greg said, go with the pro subs if it will be used exclusively outdoors. The TAT could manage outdoors but there are much better options (like T39). Well guys, I do see there is many more options ...

Re: AutoTuba Plan Question

I advise looking at the youtube section here. I made a posting of someone elses AT in a blue sedan. One 8" is all it takes! My BAT hasn't seen anywhere near full power. 300w at 8ohm to make crazy stupid loud with dual 8". Mine is 8ohm and stupid loud enough to shake the mirrors with it tu...

Re: AutoTuba Plan Question

If it's 300W either way, probably not . Depends on the amp. Typically, power output at 4 ohms is higher than at 8 ohms because the amp is delivering more current at the same voltage. If your choices are 4 or 8 ohms total, and you're using a 4 ohm driver, it looks like series wiring is your only opt...

Re: AutoTuba Plan Question

Thanks for all the response guys. I am in the process of purchasing the dual 8" but wondering how will I wire the 2 speakers to get the most out of the amp? I am using an amp that push 300 RMS Watts @ 4 or 8 Ohms. The JBL 8" sub that was recommended is a single 4 Ohms, if using two of them...

Re: AutoTuba Plan Question

You just increase the width of all the panels to 30". You put in braces for every 8 inches of width, so for a 30" externally wide cab with 29" internals, i'd use 2 braces per panel :) Ok, got you on the first part but on the second part you mentioned, "put a brace every 8" ...

Re: AutoTuba Plan Question

For maximum output I'd recommend a Dual JBL GTO 804 setup...$20 more than the MCM for a better built driver that has more power and displacement. You can get them direct from JBL off ebay for $56 shipped (USA) You're correct, its not a recommended driver but many people have used it with great succ...

Re: AutoTuba Plan Question

I did not asked if they are many other subs, I asked based on the plan, which one was better for the use, as the price range are different as well? The 3 mentioned 8" drivers have approximately the same output. I asked you where you are from because some drivers are easier to come by than othe...

Re: AutoTuba Plan Question

1. 10" for highest single woofer output. You could build it with a dual 8" for even more output. 2. Plan is for both sizes, everything except the holes in the baffle is unchanged no matter which size woofer you pick. 3. The wider you go, the more sensitivity you get - within the max width...
